The three main theories that explain how these things work are sea-floor spreading‚ continental drift‚ and plate tectonics. These are the theories that give us explanation as to why the continents move‚ how plate tectonics work‚ etc. These theories were formed by different scientists and with different forms of evidence‚ some scientists

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that
